  • the present invention relates to the investigation of the authenticity of objects.
  • the invention more particularly relates to a method, device and computer program product for investigating an object, a method, authentication data handling device and computer program product for enabling investigations to be performed about an object as well as to a system for authenticating an object.
  • Illegal copying of objects is a big problem for companies, organisations and individuals. Illegal copying involves such things as copying products to be sold, counterfeiting, as well as copying of security items, such as identity cards, credit cards, bank cards and certificates. Counterfeiting is an increasing problem for manufacturers and users. Through counterfeiting copies of goods appear that resemble the goods of the rightful owners. This can lead to considerable economical losses for the companies that provide products.
  • an object may be a product or the packaging provided for a product.
  • the objects are here identified by their unique code.
  • a system for identifying a code then normally involves the reading of the code, which code is attached to or integrated into the object. Reading of the code is then performed using a reading device.
  • the code is originally in a non-numerous mode like an image, a barcode, or a combination of properties or numeric values, that information is used for calculation of an identification number, an ID.
  • the object is uniquely identified by its code, and it's ID.
  • the code and the ID can be identical or unambiguously correlated to each other.
  • the ID is entered into a system which enables information exchange.
  • the system provides information related to the specific ID, which information has been stored to the system at an earlier stage.
  • systems for providing information about the whereabouts of an item by reading the item's unique ID are known. This is commonly used in track & trace systems. It is also known in the art that the unique ID of an item or product can be used for authenticity requests.
  • For authentication of a product it is checked whether the product's ID has been 5 issued by the manufacturer and whether it is currently in circulation.
  • the authentication database of issued IDs is maintained by the manufacturer or by a third party on behalf of the manufacturer.
  • the database can also contain further product-related data.
  • Systems providing track & trace or authentication information are either based on a o centralized database or the database is distributed among several information providers. In the latter case software is used for compiling the information from several information providers.
  • the information can be exchanged remotely as long as a connection is established between a requesting party and database.
  • connection to the centralized or distributed database can be made via a network connection.
  • the network can be a private network or it can be internet-based. It can also include additional telecommunication means like mobile phones or Bluetooth etc.
  • the information which is stored in connection to track & trace information related to a product is usually product name, tracking history (where and when the ID of an item has 0 been read), expiry date of product, and further product description (for example dosage and package size).
  • Connected to the network are at least one or several databases for maintaining the database information.
  • Connected to the network are also one or more reader or interface 5 devices which enable input of ID for requests or for registration of a reading event.
  • RFID One technology which is not yet commonly used but often mentioned is RFID. It is a 5 common opinion that an item ID provided by a chip from an RFID tag is considered to be more secure than printed versions of codes since the RFID chips themselves are hard to copy. However, RFID is currently not cost-effective for item-level use for most products.
  • Systems are also known in the art for printing or integration of security features to a product.
  • devices are used for detecting and controlling security features on products.
  • security features which have been applied to products are: fluorescent markers in packaging materials, metal threads in banknotes, micro-text printing, code printing, taggants, and many, many others.
  • signature the general term signature is used here.
  • the signatures are either detected on-site by appropriate equipment (for example an UV- lamp is used to look at UV-fluorescent features), or specialized readers that signal authenticity in case they detect a certain fluorescence pattern.
  • proprietary signatures are read by proprietary readers designed for detection of the proprietary signature.
  • Systems are known in the art for verification of intrinsic properties which identify an object uniquely, for example scanning of the surface structure of a paper, see for example WO 2005/088533.
  • the scanned information is then compared with information representing the original scan.
  • This information can be retrieved from a database.
  • Either a known database is searched for a certain signature or a pointer is used to point at the corresponding signature of the original object with the same ID.
  • the ID can be the pointer used for finding or identifying the corresponding signature.
  • the signature can also be stored in the object itself, for example as printed coded information, like in a Datamatrix code.
  • a disadvantage with these technologies is that a user has to be aware of the security features of the object and often a non-standard device is required for detection of a certain signature.
  • Some security features are covert, i.e. hidden, in order to make it more difficult for counterfeiters to copy those security features. Details about those hidden technologies are often only revealed to a selected group of users and the technology is thus for instance not applicable in a wide or open supply chain, for example.

L'invention concerne un procédé, un dispositif et un produit logiciel d'étude d'un objet. L'invention concerne également un procédé, un dispositif de traitement de données d'authentification et un produit logiciel permettant de mener des études relatives à un objet, ainsi qu'un système d'authentification d'un objet. Le dispositif (12) d'étude d'un objet comprend un module (22) d'obtention de l'identité de l'objet servant à obtenir un code (C) associé à l'objet (14), et un module (24) de mesure de propriétés de matériaux servant à mesurer des propriétés de matériaux (P1') de l'objet (14) à l'aide de données de spécification de mesure liées à l'objet (14) et obtenues auprès d'une base de données d'authentification en fonction de données (ID1) relatives au code (C). Le code (C) et les propriétés de matériaux (P1') mesurées produisent une combinaison d'informations permettant d'identifier l'objet sans ambiguïté.
